Agriculture is of the upmost importance to the world. Not only does agriculture essential to providing foodstuffs world-wide it is of critical economic importance to the economy of most, if not all countries. Three factor that can impact the yields of agricultural crops are plant disease, unfavorable growth conditions and cultivation inefficiency.

Losses from infectious plant diseases can have catastrophic humanitarian impact, where crop losses result in hunger, famine and starvation. In addition losses from plant diseases also can have a significant economic effect, causing decreased revenue for crop producers and distributors and higher prices for consumers. In situations where infectious plant disease-control methods are absent or limited, annual losses of 30% to 50% are common for major crops. Conventional plant agent technologies based on agricultural chemicals have improved agricultural productivity. However, agricultural chemical use has fallen into disfavor due to its negative consequences such as, e.g., increased cost to consumers and decreased revenue for crop producers and distributors. In addition, there is increasing public concerns regarding the negative impacts of agricultural chemicals on the environment. As such, protection of agriculturally important crops from plant diseases is crucial in improving crop yields.

Crop plants in different ecosystems around the world are also exposed to unfavorable growing conditions that negatively affect the health and vigor of the plants. These less than ideal conditions are typically due to soil or weather conditions, or various stresses including extremes of temperature, disadvantageous relationships between moisture and oxygen, toxic substances in the soil or atmosphere, and an excess or deficiency of an essential mineral. Such factors can reduce productivity of the crops to a greater or lesser degree, even under good growing conditions. As such, improving growing conditions of agriculturally important crops is important in improving crop yields.

Lastly, increased global population growth together with a concomitant decrease in land used for agriculture has increased the pressure to not only optimized crop productivity but also increase cultivation efficiency. In addition, demand for enhanced crop yields will only increase as both increases world-wide population growth and decreases in agriculture land used continues. As such, enhanced productivity of agriculturally important crops is vital in improving crop yields.

Accordingly, there is a great need for an environmentally-friendly treatments that will increase the health and vigor of plants, whether the plants are stressed by plant disease, by poor growing conditions, or even when the plants are healthy and/or grown under favorable conditions, but increased cultivation efficiency and productivity is needed. Such treatments should also reduce the amounts of, if not completely dispense with, agricultural chemicals in order to safeguard human welfare and the environment.

DETAILED DESCRIPTION

A plant becomes diseased when it is continuously disturbed by some causal agent that results in an abnormal physiological process that disrupts a plant's normal structure, growth, function, or other activities. This interference with one or more of a plant's essential physiological or biochemical systems elicits characteristic pathological conditions or symptoms. Plant diseases are caused by a pathogenic organism such as a fungus, bacterium, mycoplasma, virus, viroid, nematode, or parasitic flowering plant. An infectious agent is transmissible, being capable of reproducing within or on its host and spreading from one susceptible host to another. Plant diseases can be broadly classified according to the nature of their primary causal agent. Such primary causal agents include viruses, microorganisms like fungi and bacteria, and animals like nematodes. However, one difficulty in treating a plant disease caused by such primary causal agents is that they are typically protected from the environment by some sort of structure. These protective structures not only essential in maintaining the health of these causal agents, but also helpful in shielding these causal agents from compounds designed to destroy them.

A complete virus particle, known as a virion, consists of nucleic acid surrounded by a protective coat of protein called a capsid. The capsid encloses the genetic material of the virus and consists of several oligomeric structural subunits made of protein called protomers. Some viruses are enveloped, meaning that the capsid is coated with a lipid membrane known as the viral envelope. The envelope is acquired by the capsid from an intracellular membrane in the virus' host; examples include the inner nuclear membrane, the golgi membrane, and the cell's outer membrane.

Microorganisms such as, e.g., bacterium, mycoplasma (bacteria without a cell wall) and certain fungi, secrete a polymeric conglomeration of biopolymers, generally composed of extracellular nucleic acids, proteins, and polysaccharides, that form a matrix of extracellular polymeric substance (EPS). The EPS matrix embeds the cells causing the cells to adhere to each other as well as to any living (biotic) or non-living (abiotic) surface to form a sessile community of microorganisms referred to as a biofilm or slime layer. A biofilm colony can also form on solid substrates submerged in or exposed to an aqueous solution, or form as floating mats on liquid surfaces.

There are five stages of biofilm development, initial attachment, irreversible attachment, maturation I, maturation II and dispersion. Biofilm formation initially begins with the attachment of free-floating planktonic microorganisms to a surface. These first colonists adhere to the surface initially through weak, reversible adhesion via van der Waals forces. If not immediately separated from the surface, these first colonists become permanently anchored through secretion of the EPS matrix and formation of cell adhesion structures such as pili (irreversible attachment). Once colonization has begun, the biofilm grows through a combination of cell division of embedded microorganisms and new recruitment (Maturation I and II). In addition to the extracellular biopolymers secreted by the microorganisms, a biofilm can also incorporate material from the surrounding environment, including but not limited to minerals, soil particles, and biological components. Maturation I and II is where the biofilm is established and may only change in shape and size. The final stage of biofilm formation is known as dispersion, where microorganisms are released from the biofilm to enter the planktonic growth phase in order to spread and colonize new surfaces.

Microorganisms living in a biofilm are physiologically distinct and have significantly different properties from free-floating planktonic microorganisms of the same species. One reason for these differences is because the biofilm protects the microorganisms from the environment and allows them to cooperate and interact in various ways. For example, a biofilm increased the resistance of microorganisms to detergents and antibiotics. In addition, lateral gene transfer is greatly facilitated in biofilms and leads to a more stable biofilm structure. Microorganisms within a biofilm can also communicate with each other via quorum sensing (QS) using products such as N-acyl homoserine lactone (AHL). As such, biofilms play essential and critical roles in protecting microorganisms by insulating them from potentially harmful interactions with the environment.

Larger organisms also are protected from the environment by some sort of structure. Nematodes have a cuticle, a polymerized, proteinacious extracellular matrix. The cuticle of nematodes is formed when a mostly syncial epidermal cell layer, termed hypodermis, secretes various proteins from its apical membranes that are then extensively cross-linked by peroxidases on the outer surface of the hypodermis to form a cuticle. The major component of this flexible cuticle are members of the collagen superfamily and cuticlins, a highly cross-linked insoluble class of proteins. Overlying the cuticle is the lipid-rich, trilaminar epicuticle that is itself overlaid by a loosely associated, glycoprotein-rich, negatively charged surface coat (or glycocalyx). This multi-functional extracellular structure creates a highly impervious barrier that protects nematodes from desiccation and pathogenic infection as well as creates a structural framework that maintains its body morphology and integrity, prevents mechanical damage by environmental insults, and enables locomotion via attachments to body-wall muscles. As such, the nematode cuticle plays essential and critical roles in preserving the integrity of the animal and its interactions with the environment.

Thus, protective structures present in primary causal agents of plant diseases, such as, e.g., viruses, bacteria, fungi and nematodes is not only essential for the survival of these agents, but also protects them from the environment. Thus, a treatment that disrupts or otherwise destroys a protective structure of a primary causal agents of plant diseases would be of great benefit.

Plants, or green plants, are multicellular eukaryotes of the kingdom Plantae that form the clade Viridiplantae. Green plants includes the flowering plants, conifers and other gymnosperms, ferns, clubmosses, hornworts, liverworts, mosses and the green algae, but exclude the red and brown algae, the fungi, archaea, bacteria and animals. Plants are characterized by obtaining most of their energy from sunlight via photosynthesis using chloroplasts. Chloroplasts contain chlorophylls a and b, which gives them their green color. Plants are also characterized by having a thick cell wall of cellulose, a central vacuole for storage, plastids for storage of pigments, sexual reproduction, modular and indeterminate growth, and an alternation of generations, although asexual reproduction is also common.

A typical plant is structurally organized into two primary divisions, the root system and the shoot system. The root system is usually underground and comprises primary and lateral roots as well as modified stem structures such as tubers and rhizomes. This system functions to anchor a plant in the soil, absorb water and nutrients from the ground, transport water and nutrients throughout a plant, store food produce certain hormones. The shoot system is usually above ground and comprises stems, leaves and the reproductive organs. This system functions to elevate a plant above the soil, conduct photosynthesis, conduct reproduction, transport water and nutrients throughout a plant, store food and produce hormones.

Plants containing vascular tissues which distribute resources throughout plant are referred to as vascular plants. Vascular plants, also known as tracheophytes, are defined as those land plants that have lignified vascular tissues (the xylem) for conducting water and minerals throughout a plant and specialized non-lignified vascular tissues (the phloem) to conduct products of photosynthesis. Vascular plants include the clubmosses, horsetails, ferns, gymnosperms (including conifers) and angiosperms (flowering plants). Scientific names for the group include Tracheophyta and Tracheobionta.

Xylem is a vascular tissue that on maturity is composed of dead cells. Xylem provides unidirectional transport of xylem sap from the roots up to and throughout a plant. Xylem sap includes water, soluble mineral nutrients and inorganic ions, although it can contain a number of organic chemicals as well. Movement of xylem sap through xylem is passive, relying on capillary action to provide the force that establishes an equilibrium configuration that counteracts gravity. This capillary action is achieved principally through two mechanisms, transpirational pull and root pressure. Transpirational pull is due to a surface tension created by evaporation of water from the surfaces of cells in the leaves which causes a negative pressure in the xylem that generates enough force to pulls xylem sap upwards from the roots and soil. Root pressure is due to osmosis created by the more negative water potential of the root cells relative to the soil due to higher solute concentrations which causes a positive pressure that forces xylem sap up the xylem towards the leaves.

Phloem comprises living vascular tissue composed of 1) conducting cells called sieve elements that form tubes; 2) parenchyma cells, including both specialized companion cells or albuminous cells and unspecialized cells; and 3) supportive cells, such as fibres and sclereids that provide mechanical support. Sieve elements lack a nucleus and have very few organelles, so they rely on companion cells or albuminous cells for most of their metabolic needs. Phloem provides multi-directional transport of photosynthate (or sap) made by the photosynthetic areas of a plant (principally the leaves) to all other parts of a plant where needed, especially the non-photosynthetic parts of a plant, such as the roots, or into storage structures, such as tubers or bulbs. Photosynthate is a water-based solution rich is sugars and other soluble organic nutrients made during photosynthesis. Movement of photosynthate through the phloem is driven by positive hydrostatic pressures. This process is termed translocation, and is accomplished by a process called phloem loading and unloading. Cells in a sugar source “load” a sieve-tube element by actively transporting solute molecules into it. This causes water to move into the sieve-tube element by osmosis, creating pressure that pushes the sap down the tube. In sugar sinks, cells actively transport solutes out of the sieve-tube elements, producing the opposite effect.

The root system is the organ of a plant that typically lies below the surface of the soil. Structurally, a root is composed of an epidermis, a cortex, an endodermis, a pericycle and a vascular system. The epidermis is the outer layer of cells. The cortex is the primary structural tissue of the root bound on the outside by the epidermis and on the inside by the endodermis. The endodermis separates the cortex from the pericycle, the tissue from which lateral (or branch) roots arise from. In the center of a root is the vascular tissue comprised of xylem and phloem. A root system comprises a primary root, lateral roots and root hairs and can be divided into three regions of growth. A zone of maturation is the portion of the root system that comprises the mature portion of the primary root, lateral roots and root hairs that is absorbing water and nutrients from the soil and transporting them through the xylem into the shoot system. The zone of elongation is where newly divided cells are enlarging. The meristematic zone is composed of the root tip meristem and the root cap and is the zone where cell division and new cell growth occurs.

Root hairs are absorptive unicellular extensions of epidermal cells of a root. These tiny, hair-like structures function as the major site of water and mineral uptake. There are beneficial microorganisms associated with root hairs which form a beneficial, symbiotic relationship with a plant. Mycorrhizae are soil fungi that appear to expand the root's contact with the soil profile, enhancing water and nutrient uptake. Rhizobium is a soil bacterium that make atmospheric nitrogen available to plants, typically by forming nodules on the roots of plants.

The proper transportation of both xylem sap and photosynthate is essential for a plant's survival. As such, facilitation of this transportation process will benefit the health of a plant. For example, improved absorption at the root hairs results in increased amounts of water, minerals and other nutrients needed by a plant for growth. Likewise, better xylem sap and photosynthate flow through the vascular tissue ensures for effective and efficient synthesis of compounds and energy needed to sustain and continue plant growth.

On the other hand, any impediment that disrupts or halts the movement of xylem sap and photosynthate affects the health of a plant. For example, disturbance of transpirational pull due to high temperatures, high humidity, darkness or drought dramatically decrease the negative water pressure in the xylem resulting in poor flow of xylem sap. Likewise, disturbance of root pressure due to poor water and nutrient absorption by root hairs due to unfavorable environmental conditions can significantly reduce the positive water pressure in the xylem resulting in poor flow of xylem sap. As another example, disruption of photosynthate flow in phloem results in poor distribution of nutrients. In any of these case, such flow disruptions can result in wilting, withering, stunted grow and reduced reproduction as well as increased susceptibility to plant diseases and unfavorable environmental conditions. With respect to agricultural, such flow disruptions ultimately result in reduced yields of crops. Thus, a treatment that facilitates, maintains or enhances xylem sap and photosynthate flow in xylem and phloem respectively would be of great benefit.

Irrigation is the artificial application of water to the land or soil. It is used to assist in the growing of agricultural crops, maintenance of landscapes, and revegetation of disturbed soils in dry areas and during periods of inadequate rainfall. Irrigation also has a few other uses in crop production, which include protecting plants against frost, suppressing weed growth and preventing soil consolidation. In contrast, agriculture that relies only on direct rainfall is referred to as rain-fed or dryland farming.

The goal of irrigation is to supply an entire field uniformly with water, so that each plant has the amount of water it needs, neither too much nor too little. Overhead or sprinkler irrigation is a system where water is distributed under high pressure through a piped network to one or more central locations within a field and distributed by overhead sprinklers or guns. Sprinklers can also be mounted on platforms that can be manually or automatically moved to different regions of the field. Center pivot, traveling sprinkler, lateral move and wheel line irrigation are types of overhead irrigation methods. Localized irrigation is a system where water is distributed under low pressure through a piped network, in a pre-determined pattern, and applied as a small discharge to each plant or adjacent to it. Drip, spray or micro-sprinkler and bubbler irrigation are types of localized irrigation methods. Localized irrigation methods can be the most water-efficient methods of irrigation because they deliver only the amount of water needed and minimize evaporation and runoff.

Most commercial and residential irrigation systems are “in ground” systems, meaning that everything is buried in the ground. With the pipes, sprinklers, emitters (drippers), and irrigation valves being hidden, it makes for a cleaner, more presentable landscape without garden hoses or other items having to be moved around manually. This does, however, create some drawbacks in the maintenance of a completely buried system.

Irrigation can lead to a number of problems. For example, the piped network of overhead and localized irrigation systems can become clogged due to growth of algae and other microorganisms creating biofilms, leading to aberrant water distribution. Such poor water distribution can cause unfavorable growing conditions that negatively affect the health and vigor of a plant. For example, inconsistent water distribution lead to an under or over irrigation of portions of a field due to unequal uniformity in distribution, increase soil salinity with consequent toxic salt build-up on soil surface due to under irrigation, crop failure due to under or over irrigation and increase prevalence in plant diseases. Thus, a treatment that facilitates, maintains or enhances water flow in localized and overhead irrigation systems would be of great benefit.

Mold refer to any fermentation mold that can be produce the needed enzymes for a fermentation reaction that results in, for example the production of alcohols like ethanol or acids like acetic acid, lactic acid and/or succinic acid. A non-exhaustive list of particular mold genera useful in a fermentation reaction disclosed herein include, but is not limited, Aspergillus. A non-exhaustive list of particular mold species useful in a fermentation reaction disclosed herein includes, but is not limited, A. acidus, A. fumigatus, A. niger, A. oryzae, and A. sojae.

It will be appreciated that actual amounts of the various types of enzymes produced will be dependent on a number of factors including the types of molasses and sugar used in preparing the fermentation mixture. However, again it is believed that, in utilizing the molasses and raw sugar, optimum enzyme yields and activity are obtained. In an embodiment, the amount of yeast useful in preparing a fermenting medium disclosed herein may be between about 0.2% and about 5% by weight, and preferably between about 1% and about 3% by weight. It will be appreciated that specific amounts of the yeast utilized may be varied to yield optimum compositions desired.

The presence of a small amount of inorganic catalyst such as a magnesium salt enhances the activity of the enzymes not only during the fermentation reaction but thereafter in the product composition in attacking and decomposing the organic waste materials. A preferred magnesium salt is magnesium sulfate. The amount of magnesium salt useful in preparing a fermenting medium disclosed herein may be between about 0.1% and about 5% by weight, and preferably between about 1% and about 3% by weight. It will be appreciated that specific amounts of the magnesium salt utilized may be varied to yield optimum compositions desired.

To prepare a fermented microbial supernatant, the molasses, sucrose and magnesium salt are added to a suitable amount of warm water. Although the specific amount of water used is not particularly critical, typically suitable amounts of water are from about 2 to about 20 times the total weight of the other ingredients of the fermenting medium used in the fermentation reaction. This amount of water is sufficient to facilitate easy admixture as well as to activate the yeast, bacterial and/or mold and dissolve the other materials. In addition, the temperature of the water cannot be too hot such that the heat inactivates the malt and yeast enzymes needed for fermentation. Thus, for example, water temperatures greater than about 65° C. must be avoided and preferred temperatures are between about 25° C. to about 45° C. The use of cold water may result in unduly slow fermentation reaction rates and, thus, should also be avoided where increased reaction rates are desired. After the molasses, sugar and magnesium salt are effectively mixed and dissolved, the malt and the yeast are added, the mixture stirred and allowed to set until fermentation is essentially complete. The reaction time may be between about 2 and about 5 days at temperatures between about 20° C. and about 45° C. Completion may be readily ascertained by noting that the effervescence of the reacting mixture has substantially subsided. At the end of the fermentation reaction, the fermented microbial culture is centrifuged to remove the “sludge” formed during the fermentation. The resulting fermentation supernatant (typically about 90% to about 98% by weight) is collected for subsequent treatment.

The combination of the nonionic surfactant and the treated fermented microbial supernatant in a plant agent composition disclosed herein results in an accelerated in situ chemical reactions of the molecular structures, particularly chemical bonds present in polysaccharide and lipid-based components, of 1) the one or more components present in the protective structure of a causal agent of a plant disease; 2) the one or more components blocking xylem sap and/or photosynthate flow in a plant; or 3) the one or more components blocking water flow in an irrigation system. These in situ chemical reactions dissolve, disperse, or otherwise disrupt 1) the one or more components of the protective structure of the causal agent, resulting in its death through disruption of one or more essential physiological processes; 2) the one or more components that block xylem sap flow in xylem and/or photosynthate flow in phloem, resulting in improved transport of water and nutrients that will maintain and/or enhance the health and vigor of plants; or 3) the one or more components that disrupt water flow in a pipeline network of an irrigation system, resulting in improved water distribution that will maintain and/or enhance the health and vigor of plants.

Without wishing to be limited by any theory, upon application of a plant agent composition in an aqueous environment, highly reactive, uniquely structured, ultra-fine microbubbles are spontaneously formed. These “functionalized” microbubbles comprise an outer “highly reactive” shell composed of one or more nonionic surfactants and components from the treated fermented microbial supernatant and an inner core containing air. The “highly reactive” shell enables a dramatic increase in the mass transfer of oxygen in an aqueous environment and an accelerated bio-catalysis of the molecular structures of compounds, which in combination provide a synergistic functionality. With respect to mass transfer of oxygen, this functionality increases transfer rates of oxygen and raises the level of dissolved oxygen in an aqueous environment which far exceeding the solubility limits anticipated by Henry's Law, and, are at levels that simply cannot be achieved through mechanical aeration systems. It appears that components from the treated fermented microbial supernatant interfere with the ability of the nonionic surfactants to create a well-organized micellar shell. The result is a loose molecular packing of these fermentation components and surfactants that “functionalized” the shell to be more gas permeable, thereby creating more favorable conditions for mass gas transfer. As such, this oxygen transfer function increases the availability of oxygen in an aqueous environment. With respect to accelerated bio-catalysis, this functionality lowers the transition of energy required for a catalytic reaction to occur by providing a reaction platform that increases localized concentrations of reactants, enables donation of electrons and facilitate chemical reactions at electron poor sites. As such, this bio-catalysis function mediates cleavage of chemical bonds, including glycosidic and ester bonds, present in a compound. As such, the “functionalized” shell of the microbubbles have catalytic activities that like conventional enzyme systems, but without the need of any enzymes. Thus, application of a plant agent composition disclosed herein creates “functionalized” microbubbles that increase oxygen dispersion resulting in higher dissolved oxygen levels and accelerate molecular interactions resulting in catalytic breakdown of compounds.

When in contact with a protective structure of a causal agent, the “functionalized” microbubbles chemically interacts with one or more components of the protective structure in a manner that enables donation of electrons or reactions at electron poor sites that mediates cleavage of chemical bonds, including glycosidic and ester bonds, present in the one or more components. Similarly, when in contact with one or more components blocking xylem sap and/or photosynthate flow in a plant, the “functionalized” microbubbles chemically interacts with one or more components in a manner that enables donation of electrons or reactions at electron poor sites that mediates cleavage of chemical bonds, including glycosidic and ester bonds, present in the one or more components. Likewise, when in contact with one or more components blocking water flow in an irrigation system, the “functionalized” microbubbles chemically interacts with one or more components in a manner that enables donation of electrons or reactions at electron poor sites that mediates cleavage of chemical bonds, including glycosidic and ester bonds, present in the one or more components. These interactions appear to be a form of hydrolysis using beta-oxidation where, in addition to relying on the “highly reactive” shell, oxygen present in the core of the microbubble is also utilized. Thus, the properties present in the “functionalized” microbubbles works synergistically with the oxygen transfer capabilities of the core to enhance the in situ breaking of chemical bonds, including glycosidic and ester bonds present in 1) the one or more components present in the protective structure of a causal agent of a plant disease; 2) the one or more components blocking xylem sap and/or photosynthate flow in a plant; and/or 3) the one or more components blocking water flow in an irrigation system.

In addition, when in contact with root hairs, “functionalized” microbubbles increase water absorption, increase nitrogen-fixation, increase gas exchange, increase capillary action and hydrostatic pressure in vascular tissue by making the membranes of the root hairs more permeable to water transfer and providing a better microbial environment for symbiotic organisms that enhance root hair function. Such interactions improve absorption by root hairs, improve xylem sap flow through xylem and improve photosynthate flow in phloem, resulting in improved transport of raw materials, growth components and energy that will be used to maintain and/or enhance the health and vigor of plants.

Application of a plant agent composition disclosed herein can be by any method that exposes the one or more components present in the protective structure of a causal agent of a plant disease to the disclosed plant agent compositions in a manner that provides adequate disruption of one or more components of the protective structure and subsequent death through disruption of one or more essential physiological processes.

Similarly, application of a plant agent composition disclosed herein can be by any method that exposes the one or more components that block xylem sap flow in xylem and/or photosynthate flow in phloem to the disclosed plant agent compositions in a manner that provides adequate disruption of one or more components of the protective structure and subsequent improvement of transport of water and nutrients that will maintain and/or enhance the health and vigor of plants.

The efficacy of a plant agent composition disclosed herein may be monitored by determining the adverse effect, mortality, reduced causal agent population, reduced entering or infestation of one or more locations, or any other assessment of damage to a causal agent population, including, without limitation, inhibition, arrestment, or retardation of causal agent growth, inhibition, arrestment, or retardation of causal agent reproduction or inhibition, arrestment, or retardation of causal agent development, all of which are encompassed by the term “controlling”. Efficacy is also monitored by phytotoxicity to a plants that are infested with a causal agent population, tissue damage to the host plant infected with a causal agent population and any adverse effects that might be experienced by a human who is applying a disclosed plant agent composition to an infested plant, or otherwise exposed to a plant agent composition disclosed herein. Accordingly, the amount of a plant agent composition disclosed herein used in the disclosed methods or uses, meets the effective amount criteria above, and preferably has minimal or no adverse effect on ornamental and agricultural plants (such as phytotoxicity), wildlife and humans that may come into contact with such compositions.

Application of a plant agent composition disclosed herein can be achieved by any process that effectively creates microbubbles as disclosed herein and effectively exposes a causal agent sought to be controlled. For example any method that can introduce large concentrations of a gas into a plant agent composition during application is suitable because such gas introduction enables the spontaneous formation of microbubbles. Suitable application processes include, without limitation, spraying, fogging, atomizing, vaporizing, scattering, watering, squirting, sprinkling and the like. One preferred method of application is by a manual or mechanical application by irrigation, spraying, fogging, atomizing or vaporizing. Such applications provide formation of finely divided mist with sufficient aeration during the application process to create microbubbles as disclosed herein. Microbubbles exposed to a dispersion of gas in a liquid show colloidal properties and are referred to as colloidal gas aphrons (CGA). CGA differ from ordinary gas bubbles in that they contain a distinctive shell layer containing a low concentration of a surfactant.

The microbubbles formed with a plant agent composition disclosed herein appear to increase the mass transfer of oxygen in liquids. Without being bound by scientific theory, there are several possible explanations for this difference. First, the surfactants formulated into a plant agent composition disclosed herein include nonionic surfactants and/or biosurfactants which significantly alter the properties of bubble behavior. Second, a plant agent composition disclosed herein requires a much lower concentration of surfactants for microbubble formation. It has been suggested that surfactant concentrations must approach the critical micelles concentration (CMS) of a surfactant system. In a plant agent composition disclosed herein, microbubbles are formed below estimated CMCs for the surfactants used. This suggests that the microbubbles are the result of aggregates of surfactant molecules with a loose molecular packing more favorable to gas mass transfer characteristics. A surface containing fewer surfactant molecules would be more gas permeable than a well-organized micelle containing gas. Regardless of the mechanism, the tendency of a plant agent composition disclosed herein to organizes into clusters, aggregates, or gas-filled bubbles provides a platform for reactions to occur by increasing localized concentrations of reactants, lowering the transition of energy required for a catalytic reaction to occur, or some other mechanism which has not yet been described.

Anthracnose, or bird's-eye spot, refers to a group of plant diseases caused by numerous species of fungi from the genera Colletotrichum, Gloeosporium, Glomerella and Elsinoe that affect a variety of plants in warm, humid areas. Commonly infecting the developing shoots and leaves, anthracnose fungi produce spores in tiny, sunken, saucer-shaped fruiting bodies known as acervuli. Symptoms include small sunken dead spots or lesions with a raised border of various colors in leaves, stems, fruits, or flowers, and some infections form cankers on twigs and branches. Anthracnose causes the wilting, withering, and dying of tissues, though the severity of the infection depends on both the causative agent and the infected species and can range from mere unsightliness to death. Shade trees such as sycamore, ash, oak, and maple are especially susceptible, though the disease is found in a number of plants, including grasses and annuals.

Cankers may enlarge and girdle a twig or branch, killing the foliage beyond it. Canker can structurally weaken a plant until it breaks over in the wind or during an ice storm. Cankers also slow the normal healing of wounds and provide entry for wood decay or wilt producing fungi and other organisms. They are most common on plants weakened by cold or drought stresses, insect injury, nutritional imbalances, nematodes, or root rot. Cankers can be classified as annual cankers (Fusarium canker), perennial cankers (Nectria canker, Eutypella canker) and diffuse cankers (Botryosphaeria canker, Phytophthora dieback, Cytospora canker).

These examples should not be construed to limit any of the embodiments described in the present specification, including those pertaining to the plant agent compositions, or methods or uses disclosed herein.

Example 1 Preparation of Treated Fermented Yeast Supernatant 1

To prepare a treated fermented yeast supernatant, a fermentation reaction is set up in which about 1,000 L of warm water having a temperature of between about 29° C. to about 38° C. was placed in a large jacketed mixing kettle. To the water was added about 84.9 kg black untreated cane molasses, about 25.2 kg raw cane sugar and about 1.2 kg magnesium sulfate. The mixture was thoroughly blended, after which about 11.4 kg diastatic malt and about 1.2 kg baker's yeast were added and agitated slightly. The mixture is incubated at about 26° C. to about 42° C. for about 3 days, after which the effervescent reaction had subsided, indicating essentially complete fermentation. At the end of the fermentation the yeast fermentation composition is centrifuged to remove the “sludge” formed during the fermentation. The resulting fermentation supernatant (about 98.59%, by weight) was collected and sterilized by autoclaving. The treated fermented yeast supernatant can then be stored in liquid form for subsequent use. Alternatively, the treated fermented yeast supernatant can be spray dried by methods known in the art to produce a dry powder. The dry powder form can also be stored for subsequent use.

Example 4 Preparation of Plant Agent Composition

To prepare a plant agent composition, 1,000 L of hot sterile water (about 60° C. to about 65° C.) was added to 1,000 L of treated fermented yeast supernatant in a large jacketed mixing kettle. To this mixture was added about 168.8 kg of TERGITOL™ 15-S-7, a linear secondary alcohol ethoxylate, about 168.8 kg of TERGITOL™ 15-S-5, a linear secondary alcohol ethoxylate, about 67.5 kg of DOWFAX™ 2A1, alkyldiphenyloxide disulfonate, and about 67.5 kg of TRITON™ H-66, phosphate polyether ester. This mixture was thoroughly blended to effect solution. Water was then added to bring the volume to about 4,500 L and stirred until complete mixing had been obtained. The pH of the resulting plant agent composition was adjusted to from about 3.7 to about 4.2 with phosphoric acid. The pH adjusted plant agent composition was then filter sterilized to remove any microbial contamination.

The composition was found to be nonirritating to skin tissue, nontoxic and could be stored in a cool location over periods of months without any discernible loss in effectiveness or deterioration. DOWFAX™ 2A1 can be substituted with an anionic biosurfactant such as, e.g., STEPONOL® AM 30-KE, an ammonium lauryl sulfate, STEPONOL® EHS, a sodium 2-ethyl hexyl sulfate, or a combination thereof.

The composition was found to be nonirritating to skin tissue, nontoxic and could be stored in a cool location over periods of months without any discernible loss in effectiveness or deterioration.

DOWFAX™ 2A1 can be substituted with an anionic biosurfactant such as, e.g., STEPONOL® AM 30-KE, an ammonium lauryl sulfate, STEPONOL® EHS, a sodium 2-ethyl hexyl sulfate, or a combination thereof.

As an alternative to the treated fermented yeast supernatant dried powder disclosed in Examples 1-3, commercially available treated fermented yeast supernatant dried powders can be used, including, e.g., TASTONE® 154, TASTONE® 210 or TASTONE® 900.

Example 6 Rice Study

This example shows the effects of a plant agent composition disclosed herein on rice plant growth and grain production.

In one assay, the effects of a plant agent composition disclosed herein on rice seed germination, seedling height and root length was assessed. Seeds from the rice variety Oryzica 1 were divided into three groups of 100 seeds, placed in a bag and each group pre-treated for 2 minutes by immersing the bag in one of the following solutions: 1) distilled water (control); 2) a 2% solution of a plant agent composition disclosed herein (92% treated fermented supernatant and 8% surfactant); and 3) a 2% solution of a plant agent composition disclosed herein (90% treated fermented supernatant and 10% surfactant). Treated seeds were was sown in sterile sand and then placed in a soil grower for 7-10 days to allow for germination. Germination effects was assessed by determining germination percentage, height of seedling and root length. This assay was performed four times. The results indicated that seed treatments of rice seed variety Oryzica 1 showed no differences in the measured variables: germination percentage, seedling height and root length.

In another assay, the effects of a plant agent composition disclosed herein on growth of rice seedlings was assessed. Seedlings from the rice variety Oryzica 1 were divided into group of 20 seedlings and transplanted into planters with previously sterilized soil fertilized properly to meet the nutritional requirements of a good development of the rice plant. The seedlings were divided into three groups of five planters. Seedlings were treated with 2 mL of one of three solution each day for 20 days. Group 1 was treated with distilled water (control); Group 2 was treated with a 2% solution of a plant agent composition disclosed herein (92% treated fermented supernatant and 8% surfactant); and Group 3 was treated with a 2% solution of a plant agent composition disclosed herein (90% treated fermented supernatant and 10% surfactant). At the end of the 20-day period, data seedling height, stem production, and grain yield was taken.

The results indicated that Treatment Groups 1 and 2 showed significant improvement relative to Control Group 1. For example, one assessment I the ratio of stem growth to panicle (loose, branching cluster of flower) growth. The Control Group 1 showed greater stem/panicle ratio (15.4/12.2) with many long stems with very short panicle, an indicator of less grain production. Treatment Group 1 and Treatment Group 2 showed more favorable stem/panicle ratios (10.4/7.4 and 12.2/10.2, respectively) which will result in higher grain yields. Treatment Group 2 showed a better stem/panicle ratio relative to Treatment Group 1, producing long stems with good panicles. In addition, of the panicle produced, the Control Group 1 contained 13.5% vain grain (not full of rice grain), which is an indicator of sterility. Treatment Group 2 showed 6.4% vain grain and Treatment Group 3 showed 3.9% vain grain. Thus, treatment with a plant agent composition disclosed herein reduced sterility in the plants. Furthermore, Treatment Group 2 produced 14% more grains per plant and Treatment Group 3 produced 64% more grains per plant when compared to Control Group 1. Furthermore, Treatment Group 2 showed a 55% increase in root growth and Treatment Group 3 produced 104% increase in root growth when compared to Control Group 1. Taken together, significant benefits were observed when rice plants were treated with a 2% solution of a plant agent composition disclosed herein.

Example 7 Tomato Study

This example shows the effects of a plant agent composition disclosed herein on tomato plant growth and fruit production.

Tomato seedlings were grown in greenhouses in soil composed of 40% sand and 60% organic compost. Although no fertilizer or urea was used, cow manure was applied. The tomato seedlings were divided into two groups: The Control Group comprised seedlings that were drip irrigated with distilled water (control) each day for 6 months. The Treatment Group comprised seedlings that were drip irrigated with a 2% solution of a plant agent composition disclosed herein (90% treated fermented supernatant and 10% surfactant). Plants were assessed on a monthly basis for a 6-month period of time. Plant growth and fruit production were assessed.

The results indicated that Treatment Group showed significant improvement relative to Control Group. For example Treatment Group plants were stronger and more robust than the Control Group throughout the entire 6-month period. In addition, the Control Group had a 30% mortality for this study while the Treatment Group exhibited 100% survivability rate. Furthermore, Treatment Group plants were still flowering and bearing fruit for 5 months while the Control Group stopped flowering and bearing fruit after 3 months. Lastly, the final yield of the crop for the Treatment Group was over 2 times more than the Control Group yield. For example, the Control Group yielded 720 Kg of tomatoes while the Treatment Group yielded 1,715 Kg of tomatoes. Taken together, significant benefits were observed when tomato plants were treated with a 2% solution of a plant agent composition disclosed herein.

Similar studies were conducted for parsley. The results indicated that five times more parsley could be harvested from a Treatment Group treated with a 2% solution of a plant agent composition disclosed herein relative to a Control Group treated with distilled water.

Similar studies were conducted for eggplant. The results indicated 28% more eggplant could be harvested from a Treatment Group treated with a 2% solution of a plant agent composition disclosed herein relative to a Control Group treated with distilled water.

Example 8 Olive Tree Study

This example shows the effects of a plant agent composition disclosed herein on olive tree growth and fruit production.

Olive trees grown in an orchard were divided into two groups: The Control Group comprised trees that were drip irrigated with distilled water (control) over the course of two seasons. The Treatment Group comprised trees that were drip irrigated with a 2% solution of a plant agent composition disclosed herein (90% treated fermented supernatant and 10% surfactant) over the course of two seasons. Plants were assessed on a monthly basis over the study period. Plant growth and fruit production were assessed.

The results indicated that Treatment Group showed significant improvement relative to Control Group. For example, the Treatment Group yielded about 35% to about 40% more olives compared to the Control Group. More astonishingly, fruiting occurring every year for olive trees in the Treatment Group as compared to the Control Group which fruited every other year. Lastly, the taste of the oil, specifically the phenols, were enhanced, and therefore taste or quality was improved in the oil from the trees in the Treatment Group relative to the Control Group.

Similar test results were observed for walnut trees and almond trees.

Example 9 Tobacco Study

This example shows the effects of a plant agent composition disclosed herein on tobacco growth and fruit production.

Tobacco seedlings were grown in field. The tobacco seedlings were divided into two groups: The Control Group comprised seedlings that were drip irrigated with distilled water (control) each day for 6 months. The Treatment Group comprised seedlings that were drip irrigated with a 2% solution of a plant agent composition disclosed herein (90% treated fermented supernatant and 10% surfactant). Plants were assessed on a monthly basis for a 6-month period of time. Plant growth and fruit production were assessed.

The results indicated that Treatment Group showed significant improvement relative to Control Group. For example, tobacco crops from the Treatment Group showed about 40% to about 50% more growth compared to the Control Group. In addition, tobacco crops from the Treatment Group exhibited larger root growth and better survival rates of seedlings.

Similar test results were observed for cannabis, although the study was performed in a greenhouse.

In closing, it is to be understood that although aspects of the present specification are highlighted by referring to specific embodiments, one skilled in the art will readily appreciate that these disclosed embodiments are only illustrative of the principles of the subject matter disclosed herein. Therefore, it should be understood that the disclosed subject matter is in no way limited to a particular compound, composition, article, apparatus, methodology, protocol, and/or reagent, etc., described herein, unless expressly stated as such. In addition, those of ordinary skill in the art will recognize that certain changes, modifications, permutations, alterations, additions, subtractions and sub-combinations thereof can be made in accordance with the teachings herein without departing from the spirit of the present specification. It is therefore intended that the following appended claims and claims hereafter introduced are interpreted to include all such changes, modifications, permutations, alterations, additions, subtractions and sub-combinations as are within their true spirit and scope.

Certain embodiments of the present invention are described herein, including the best mode known to the inventors for carrying out the invention. Of course, variations on these described embodiments will become apparent to those of ordinary skill in the art upon reading the foregoing description. The inventor expects skilled artisans to employ such variations as appropriate, and the inventors intend for the present invention to be practiced otherwise than specifically described herein. Accordingly, this invention includes all modifications and equivalents of the subject matter recited in the claims appended hereto as permitted by applicable law. Moreover, any combination of the above-described embodiments in all possible variations thereof is encompassed by the invention unless otherwise indicated herein or otherwise clearly contradicted by context.

Groupings of alternative embodiments, elements, or steps of the present invention are not to be construed as limitations. Each group member may be referred to and claimed individually or in any combination with other group members disclosed herein. It is anticipated that one or more members of a group may be included in, or deleted from, a group for reasons of convenience and/or patentability. When any such inclusion or deletion occurs, the specification is deemed to contain the group as modified thus fulfilling the written description of all Markush groups used in the appended claims.

Unless otherwise indicated, all numbers expressing a characteristic, item, quantity, parameter, property, term, and so forth used in the present specification and claims are to be understood as being modified in all instances by the term “about.” As used herein, the term “about” means that the characteristic, item, quantity, parameter, property, or term so qualified encompasses a range of plus or minus ten percent above and below the value of the stated characteristic, item, quantity, parameter, property, or term. Accordingly, unless indicated to the contrary, the numerical parameters set forth in the specification and attached claims are approximations that may vary. For instance, as mass spectrometry instruments can vary slightly in determining the mass of a given analyte, the term “about” in the context of the mass of an ion or the mass/charge ratio of an ion refers to +/−0.50 atomic mass unit. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical indication should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques.

Use of the terms “may” or “can” in reference to an embodiment or aspect of an embodiment also carries with it the alternative meaning of “may not” or “cannot.” As such, if the present specification discloses that an embodiment or an aspect of an embodiment may be or can be included as part of the inventive subject matter, then the negative limitation or exclusionary proviso is also explicitly meant, meaning that an embodiment or an aspect of an embodiment may not be or cannot be included as part of the inventive subject matter. In a similar manner, use of the term “optionally” in reference to an embodiment or aspect of an embodiment means that such embodiment or aspect of the embodiment may be included as part of the inventive subject matter or may not be included as part of the inventive subject matter. Whether such a negative limitation or exclusionary proviso applies will be based on whether the negative limitation or exclusionary proviso is recited in the claimed subject matter.

Notwithstanding that the numerical ranges and values setting forth the broad scope of the invention are approximations, the numerical ranges and values set forth in the specific examples are reported as precisely as possible. Any numerical range or value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements. Recitation of numerical ranges of values herein is merely intended to serve as a shorthand method of referring individually to each separate numerical value falling within the range. Unless otherwise indicated herein, each individual value of a numerical range is incorporated into the present specification as if it were individually recited herein.

The terms “a,” “an,” “the” and similar references used in the context of describing the present invention (especially in the context of the following claims) are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context. Further, ordinal indicators—such as “first,” “second,” “third,” etc.—for identified elements are used to distinguish between the elements, and do not indicate or imply a required or limited number of such elements, and do not indicate a particular position or order of such elements unless otherwise specifically stated. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g., “such as”) provided herein is intended merely to better illuminate the present invention and does not pose a limitation on the scope of the invention otherwise claimed. No language in the present specification should be construed as indicating any non-claimed element essential to the practice of the invention.

When used in the claims, whether as filed or added per amendment, the open-ended transitional term “comprising” (and equivalent open-ended transitional phrases thereof like including, containing and having) encompasses all the expressly recited elements, limitations, steps and/or features alone or in combination with unrecited subject matter; the named elements, limitations and/or features are essential, but other unnamed elements, limitations and/or features may be added and still form a construct within the scope of the claim. Specific embodiments disclosed herein may be further limited in the claims using the closed-ended transitional phrases “consisting of” or “consisting essentially of” in lieu of or as an amended for “comprising.” When used in the claims, whether as filed or added per amendment, the closed-ended transitional phrase “consisting of” excludes any element, limitation, step, or feature not expressly recited in the claims. The closed-ended transitional phrase “consisting essentially of” limits the scope of a claim to the expressly recited elements, limitations, steps and/or features and any other elements, limitations, steps and/or features that do not materially affect the basic and novel characteristic(s) of the claimed subject matter. Thus, the meaning of the open-ended transitional phrase “comprising” is being defined as encompassing all the specifically recited elements, limitations, steps and/or features as well as any optional, additional unspecified ones.
